In the BJLH bin there is two constants that I cant seem to find any information on.

Platform ID (MSW) and Platform ID (LSW)

I did a search and found lots on platform, but nothing on (MSW) or (LSW).

Can someone explain what these are?

 

Yeah, if you look at a hack src, you will find that there are a total of 4 bytes, 2 words defining the platform ID. MSW = most significant word LSW = least significant word

 

Thank you. I will try to find the hack.

I should have added to my original post, What are the afects of changing these two constants?

 

nothing really, it just identifies the platform, most hacs have FFFF FFFF or 0000 0000
set for platform ID.

 

The reson I am so interested in these is my son just bought a 94 PU that prior owner installed a 383 in and it runs like crap. After looking at the tune that was done by a mail order company I see why, and we will straiten it out this weekend.

When I opened up the file I found the two constants that I have been talking about maxed out at 65535. I went back to my library of $OD bins and all were set to 0. I am just trying to figure out why they changed them, and if I should set them back to 0.

 

Gearhead, where in Oregon are you? I just opened a 1/2 dozen $0D bins, 2 had 0000 0000
and 4 had FFFF FFFF. I really don't think it matters, just ignore it. It doesn't have any effect on what you are doing. What BCC are you using as a starting point? Moates has a few 383 specific bins, not knowing what internals the 383 has will make for hours of frustration, but lots of datalogging and digging and I am sure you will sort it out. It sounds like you have a pretty good grasp of tuning.
